Optimization Of Data Structure And Algorithms In Spatial Analysis System

With the rapid development of China's socio-economic, economic statistical data and statistical information grow by geometric progression. At the same time, the government of statistics and decision-making department and the public also set a higher request to the statistical work. It needs the integration of statistical information and the spatial data, the deeply and comprehensive analysis of statistical analysis, as basis of macro-economic decision.This practical problem relates to the probability and statistics, statistical mathematical analysis, geographic information systems, and some other subjects. It can no longer meet the demand of problem using the traditional means with a single statistical analysis. Meanwhile those general geographic information systems can not directly achieve the systematic analysis requirements either.In this paper, writer analyzes the characteristics of GIS analysis system, and rationally uses the statistical analysis of mathematical methods, to explore ways to solve such problems and the characteristics of economic statistics. In the progress writer researches on the GIS system data structures and the underlying algorithm of functions, and ultimately fulfills this part of the GIS analysis system with computer.The main thesis and conclusions of the study is:(1) Combining GIS analysis methods with economic statistics, exploring the the rules and characteristics of economic statistics.(2) Building a data structure, which is suitable for the analysis system, with the characteristics of economic statistics and previous GIS data structure.(3) Researching and comparing the methods of spatial analysis in accordance with the demand of the analysis system.With the above-mentioned studies, this article seeks to combine GIS technology and the economic statistics industry, and analyzes the characteristics and laws of the economic statistical data's spatial distribution .
